Title
(EN) A METHOD FOR DRIVING A VEHICLE PLATOON
(FR) PROCÉDÉ POUR CONDUIRE UN PELOTON DE VÉHICULES
Abstract
(EN)
A control unit (20) for controlling a vehicle platoon, a computer program and a method for driving a vehicle platoon (1) having a lead vehicle (2) and a plurality of vehicles (3) following the lead vehicle (2). The method comprises the steps of providing a first mode and a second mode for driving the lead vehicle (2), by using a first brake map (29a) for the first mode and a second brake map (29a') for the second mode for braking the lead vehicle (2), wherein the first brake map (29a) gives a lower brake force (27) on the lead vehicle (2) than the second brake map (29a') for equal brake requests (22), and/or by using a first acceleration map (29b) for the first mode and a second acceleration map (29b') for the second mode for accelerating the lead vehicle (2), wherein the first acceleration map (29b) gives a lower traction force (28) on the lead vehicle (2) than the second acceleration map (29b') for equal acceleration requests (25), and shifting from the first mode to the second mode when an operator of the lead vehicle (2) has performed a predetermined driving action. The vehicle platoon can be driven with improved comfort in an energy efficient way.
(FR)
La présente invention concerne une unité de commande (20) permettant de commander un peloton de véhicules, un programme d'ordinateur et un procédé permettant de conduire un peloton de véhicules (1) comportant un véhicule de tête (2) et une pluralité de véhicules (3) suivant le véhicule de tête (2). Le procédé comprend les étapes consistant à fournir un premier mode et un second mode pour conduire le véhicule de tête (2), à l'aide d'une première carte de frein (29a) pour le premier mode et d'une seconde carte de frein (29a') pour le second mode pour le freinage du véhicule de tête (2), la première carte de frein (29a) procurant une force de freinage (27) plus faible sur le véhicule de tête (2) que la seconde carte de frein (29a') pour des demandes de freinage (22) identiques et/ou à l'aide d'une première carte d'accélération (29b) pour le premier mode et d'une seconde carte d'accélération (29b') pour le second mode pour l'accélération du véhicule de tête (2), la première carte d'accélération (29b) procurant une force de traction (28) plus faible sur le véhicule de tête (2) que la seconde carte d'accélération (29b') pour des demandes d'accélération (25) identiques, et à passer du premier mode au second mode lorsqu'un opérateur du véhicule de tête (2) a effectué une action de conduite prédéfinie. Le peloton de véhicules peut être conduit avec un confort amélioré d'une manière économe en énergie.
